ls: Ensure file names are separated by 2 spaces
We need two spaces between filenames because that is the convention followed by other implementations. More importantly, if we do not have two spaces, certain Unicode file names cause filenames to run together. In Unicode, combining characters come before the character they modify. If a filename ends in a combining character, the combining character attaches to the space that follows it, causing the space not to be visible. Having a two-space gap stops the above issue from happening. For context and a bit more information, see mailing list link below. https://www.mail-archive.com/toybox@lists.landley.net/msg05986.html
